Combine two related color manager improvements:
1. Migrate MCM/RMCM, shaper and 3DLUT HW programming to dc_plane_cm
- Continue convergence with upstream Color Manager refactor
- Migrate MCM/RMCM, shaper and 3DLUT programming for dcn401+ to dc_plane_cm
- Unify MCM programming across both legacy and 3DLUT DMA paths
- Add 3DLUT DMA broadcast support for multi-pipe planes
2. Reprogram MCM blend LUT on blend_enable falling edge
- Fix issue where SDR desktop remained desaturated after video playback
- Detect blend_enable falling edge (1->0) in surface update detection
- Force MCM LUT reprogramming on blend state change

[Why]
DCN must not gate DF C-state locally via the DCHUBBUB ALLOW_SELF_REFRESH
controls: forcing a local "disallow" during MM-stutter re-entry can wedge the
fabric and hang boot. When DCN is disallowing c-state or has invalid watermarks
we should be explicit about it rather than using the watermark force selector.
[How]
Register DCN as a client of PMFW's DF C-state arbiter and signal over DALSMC
whether DCN permits DF C-state; PMFW allows DF C-state only once every client
(including DCN) has voted "allow".
- dc_clocks.cstate_allow: last DCN vote acked by PMFW
- clk_mgr_funcs::notify_cstate_disable(clk_mgr, disable)
prepare_bandwidth and headless dc_power_down_on_boot vote Allow;
hardware_release votes Disallow; init_clocks
(D0 entry) only clears the cache (cstate_allow) so the next allow re-syncs with
PMFW.

[Why]
The dc_update_state commit interface and the dc_probe object model existed
but were not connected: there was no path to validate, commit, and program
a probe through the update pipeline, nor to read the result back. The
measurement waits on OTG frame edges and must not block fast updates.
[How]
- Move the per-commit scratch off dc_stream_state onto a dc-owned pool;
acquire at init, release on cleanup or prepare failure, serialized by the
DM global lock every commit path already holds.
- dc_update_state drives stream commits, probe-only commits, or both through
one staged init/prepare/execute/cleanup loop with a null-arg guard. prepare
releases the scratch slot on failure; cleanup releases it on success.
- Probe prepare installs the absolute probe set in place; execute calls the
perfmon programming hook in the unlocked window and latches results.
- Add resource_validate_probe_set, a context-free achievability check shared
by dc_validate_global_state (full update) and probe prepare (probe-only).
- dc_state_get_status gains a probe status class with a probe filter and a
by-type mapping; dc_validation_set gains probes/probe_count. Drop the dead
actual_* fields from struct dc_qos_info.

[Why]
The hubbub perfmon peak-bandwidth path used a monolithic function
combining counter configuration and enable in one call, and wrote results
into a caller-supplied struct outside the dc_state model. A BLS-driven
approach builds the measurement from stateless primitives, gates it to OTG
frame boundaries, and stores results in dc_state.
[How]
- Rename the peak-BW vtable members from "unbounded_bandwidth" to
"out_of_order_bandwidth" and split them into arm and start operations.
- Add the full set of perfmon BLS primitives - param structs, union
members, enum entries, executors, and hwss_add_* builders - for reset,
arm, every start_measuring_* and every get_* operation.
- Add dc_probe_status (valid, type, result union) plus probe_status[] to
dc_state.
- Replace the measure_memory_qos hook with program_perfmon(dc, context),
which writes results into probe_status[].
- dc_get_qos_info no longer calls the removed hook.

DCN 3.6+ hardware supports CRC-32 polynomial in addition to the
legacy CRC-16. Enable 32-bit CRC values per color component for
improvement of precision in display validation.
[How]
When userspace sets crc_poly_mode (0=CRC-16, 1=CRC-32) via the debugfs
interface, the value is stored in dm_irq_params.crc_poly_mode. When CRC
source configuration triggers amdgpu_dm_crtc_configure_crc_source(),
crc_poly_mode is retrieved from dm_irq_params and passed to
dc_stream_configure_crc().
In the DC layer, dc_stream_configure_crc() sets crc_poly_mode into the
crc_params structure and passes it to optc35_configure_crc(). If the
hardware supports the OTG_CRC_POLY_SEL register, the register is
programmed to select CRC-16 or CRC-32 polynomial.
When reading CRC values, optc35_get_crc() checks whether CRC32 register
masks are available. If present, it reads 32-bit CRC values from
OTG_CRC0/1_DATA_R32/G32/B32 registers; otherwise, it falls back
to reading 16-bit CRC values from legacy OTG_CRC0/1_DATA_RG/B
registers.

Add a num_analog_stream_encoders field to indicate how many
analog stream encoders are present. When analog stream encoders
are present, create them.
Additionally, add an analog_engine field to link encoders and
search for supported analog encoders in the BIOS for each link.
When connecting an RGB signal, search for analog stream encoders.
The actual DCE analog link and stream encoder is going to be
added in a subsequent commit.
v2:
Add check to see if an analog engine is really supported.

We are going to support analog encoders as well, not just digital,
so we need to make space for them in various arrays.

[Why]
Debugging underflow issues frequently requires knowing the
HW state at the time of underflow. To enable capturing this
HW state information, interface functions are needed for the
various DC HW blocks.
[How]
This change adds the interface functions to read HW state for
the following DC HW blocks:
- HUBBUB
- HUBP
- DPP
- MPC
- OPP
- DSC
- OPTC
- DCCG

[Why]
dml2 folder contains all logic for all versions of DML2
This is currently DML2.0 and DML2.1.
Rename dml2 to dml2_0 folder to reflect this better (dml2_0
for DML2.0).
[How]
Rename dml2 to dml2_0 folder and update dml2 references to
use dml2_0 folder.
